Question

A body starts from rest with uniform acceleration of 2 $m{s}^{-2}$.Find the distance covered by the body in 2 s.

Answer 1

Initial velocity u = 0
Acceleration a = 2 m/s²
Time t = 2 s
Let ‘S’ be the distance covered.
Using the second equation of motion,
S = ut + $\frac{1}{2}$at²
= 0 + $\frac{1}{2}\times 2\times 2^2$
= 4 m
